JAMESM. HARPER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE HARPER SUPPLY COMPANY, A CORPORATION OF ILLINOIS.

SAD-IRON.

Be it known that I, JAMES M. HARPER, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sad-Irons, of which the following is a specification.

This invention relates to that type of sadirons, in which the handle is made detachable from the sad-iron body, and the present improvement has for its object to provide a simple and efficient structural formation of the detachable handle by which the sad-iron body is carried and manipulated, all as will hereinafter more fully appear andbe more particularly pointed out and claimed.

In the accompanying drawings :Figure 1, is a vertical sectional elevation of my improved sad iron at line acx, Fig. 2. Fi 2, is a horizontal sectional elevation at ine x'a Fi 1 the non-conducting material being omitted. Fig. 3, is a transverse sectional elevation of the bottom part of the handle, at line x -0c Fig. 1 showing the convexo-concave shape thereof.

Similar numerals of reference indicate like parts in the different views.

Referring to the-drawings:1, re resents an open top approximately elliptica cavity formed in the sad-iron body to divide the same into a main central and inner portion 2, integrally connected to an outer shell or wall 3, by a bottom-web 4. In the construction shown the central portion of the sadiron body is provided at its respective ends with vertical lugs or extensions 2 which project upwardly into adjacent relation to the hereinafter described cover plate and are provided with screw-threaded orifices for the reception of the screws by which said cover plate is attached to the sad-iron body; While the top surface of the central portion of said sad-iron body, is in a plane below said lugs to provide an u per horizontal cavity 5, which opens into t e approximately elliptical cavity 1, aforesaid.

6, is a filling of asbestos, or other equivalent non-conducting material arran ed in the cavities 1 and 5, aforesaid, and adapted to house and insulate the top and side surfaces of the main inner portion 2 of the sad-iron body, so that the heat stored therein will be compelled to pass out through the bottom of the sad-iron, and thus maintain the same in Specification of Letters Patent. Application filed. September 19, 1904. Serial No. 225,003.

Patented. Oct. 13, 1908.

the properly heated condition for an extended period of time. a

7, is a cover plate fitting the top of the sad-iron body and secured thereto by screws 8, or other usual attaching means.

9, is a rectangular catch bar, attached in a central and longitudinal direction to the upper surface of the cover plate 7, and provided with a horizontally projecting toe 10, at one end and a vertical heel at the other end, as shown in Fig. 1.

11, is the cylindrical grip portion of the sad-iron handle, and 12, is the straight attaching bar of said handle, of convexo-concave or segmental form in cross section and having integrally formed flat angular arms 13, the lower parts of which are merged into the straight attaching bar. The arms 13 are adapted for attachment to the respective end of'the cylindrical grip 11, by screws or other usual attaching means.

14, is a longitudinally extending slot formed in the bar 12, aforesaid, for the passage of the catch bar 9, and the arrangement is such that'a portion of the bar 12 adjacent one end of the slot is adapted to engage beneath the toe 10, of the catch bar 9, by an independent forward movement of the sadiron handle upon the sad-iron body, as usual in the present type of fastenings for sad-iron handles.

15, is a, holding dog pivoted to a pair of vertical ears formed on the bar 12, at opposite sides of the rear end of the slot, and formed with a curved face adapted to drop behind the end of the catch bar 9, opposite the toe 10, to lock the said bar 12, in engagement with the catch'bar 9, as illustrated in Fig. 1.

edges of said bar will have effective bearing upon the top plate of the sad-iron body to prevent lateral sway between the parts; stiffness will be imparted to the bar to resist a tendency to fiexure of the same in use, and great lightness can be attained with ample rigidity and strength in the handle.

Having thus fully described my said invention, What I claim as new and desire to secure by Letters Patent is A sad iron comprising a body, a cover plate secured to the body, a horizontal longitudinally arranged rectangular catch bar, secured to the cover late, and having, at one end, a horizontal orWardly projecting and overhanging toe, and at the other end, a vertical heel, a removable handle consisting of a cylindrical grip, a straight attaching bar of conveXo-concave shape in cross-section, seating on the cover plate, and having a longitudinal slot through which the catch bar projects, and With the toe of Which the attaching bar engages, a pair of vertical ears, at one end of the attaching bar, on opposite sides of the longitudinal slot, and flat angular arms, having their lower ends merged into the attaching bar, and their upper ends secured llat against the cylindrical grip, and a longitudinally arranged dog having its rear end pivoted to the vertical ears, and its forward end curved and adapted to enter the longitudinal slot and to bear against the vertical heel of the catch bar so as to seat the attaching bar beneath the horizontal toe and lock the handle to the cover plate.

Signed at Chicago, Illinois, this 15th day of Sept. 1904.

JAMES M. HARPER.
